Format-neutral capability facts a frontend projects from its raw source inventory before any scale plan or candidate exists.

This is deliberately coarser than a format’s own raw capability manifest (for example animsmith_gltf::GltfCapabilityManifest): it only carries the flags this module’s planning needs to fail closed on an unsupported domain, per DESIGN.md Appendix D §D.4. A frontend projects its richer, format-specific manifest down to these flags.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

coverage: ScaleCapabilityCoverage

Whether the projection covers the complete source domain.

morphs_present: bool

A morph target is present.

morph_weights_present: bool

Static or animated morph weights are present.

whole_document_morphs_preservable: bool

The format adapter owns exact preservation of every present morph payload for whole-document conversion.

Presence alone is never permission: this witness is set only after a raw adapter has validated its operation-specific write set and proof.

cameras_present: bool

A camera is present.

lights_present: bool

A punctual light is present.

instancing_present: bool

GPU-instancing data is present.

unregistered_extensions_present: bool

An extension is not covered by a registered length-field handler.

extras_present: bool

Non-null application-specific extras are present.

unknown_source_members_present: bool

A JSON/source member outside the modeled schema was ignored.

non_triangle_primitives_present: bool

A non-triangle-list primitive is present.

unsupported_vertex_attributes_present: bool

A vertex attribute outside the normalized writer subset is present.

secondary_skin_influences_present: bool

A secondary skin-influence set is present.

inverse_bind_issues_present: bool

An inverse-bind accessor is missing, empty, mismatched, or unreadable.

unsafe_accessor_layout_present: bool

A scale-bearing source layout cannot be safely bounded or rewritten.

external_resources_present: bool

An external (non-embedded) resource is referenced.

Implementations

impl ScaleCapabilityFacts

pub fn is_supported(&self) -> bool

A capability projection declaring complete coverage and no unsupported domain for either operation.

This operation-agnostic query stays conservative for callers that do not yet have an operation in hand. Planning uses Self::is_supported_for so a format adapter that owns raw morph preservation can admit morphs for whole-document conversion without weakening the rest/bind boundary.

pub fn is_supported_for(&self, operation: ScaleOperation) -> bool

Whether this complete projection is supported for operation.

Morph targets are deliberately operation-specific. A whole-document format adapter may scale raw POSITION deltas and preserve dimensionless weights outside crate::Document; rest/bind still refuses every morph because its raw preservation proof has not been defined. All other capability domains retain the same refusal for both operations.
